Hi Gert, Quick though: Better aggregation, less fragmentation, bigger address blocks. I think this improves the efficiency. Moving the HD-ration seems to me more useful in terms of managing the way LIRs get their prefix, while changing the end-user prefix, is the easier way, but the most hurting one in terms of facilitating the grow of home networks (which in turn means innovation and more business for ISPs). Just look for the big allocations (/19, /20). They are fair with the today HD-ratio, but are they realistic ? I'm not asking to replace those, on the contrary, I'm happy that some people show clear deployment steps at a big scale, but what I don't think we should do now is a restriction, again, to the end users. If so, then let's go directly to NAT with IPv6 :-( On the other hand, do we really believe is a problem to have a protocol that might last for "only" 60-100 years? I don't really think so, as it will be probably replaced in 40-50 years already, because many more additional reasons (may be will not be IP at all). Regards, Jordi

I think if we really want to go into this direction, the HD ratio modification seems a better idea. I actually have already thought long time ago that we can't compare in terms of efficiency IPv4 with IPv6, so no reason for keeping the same ratio.
Why do you assume that the achievable efficiency isn't comparable?
IPv6 has some bonuses ("all end-customer networks have the same size") and some drawbacks ("you need to achieve a much higher aggregation level if your internal routing system is ever going to cope with the sheer number of customer networks"), so overall efficiency "should" be similar.
